2 questions for y'all today

1st is in 18.4 weeks and and since like 17 weeks I get like these thumps at first I thought there were gas cuz it feels like bubbles popping but after they started coming in a pattern I'm thinking baby and I can feel where he's at and that's where the bubbles come from
     2nd question is my 6 week old puppy is so attached to me now he's always by my side never wants me to leave is this normal
